      powerpc/mm: Fix Respect _PAGE_COHERENT on classic ppc32 SW TLB load machines · 345953cf
      Kumar Gala 提交于
      Grant picked up the wrong version of "Respect _PAGE_COHERENT on classic
      ppc32 SW" (commit a4bd6a93)
      
      It was missing the code to actually deal with the fixup of
      _PAGE_COHERENT based on the CPU feature.

      ucc_geth: Fix oops when using fixed-link support · 61fa9dcf
      Anton Vorontsov 提交于
      commit b1c4a9dd ("ucc_geth: Change
      uec phy id to the same format as gianfar's") introduced a regression
      in the ucc_geth driver that causes this oops when fixed-link is used:
      
      Unable to handle kernel paging request for data at address 0x00000000
      Faulting instruction address: 0xc0151270
      Oops: Kernel access of bad area, sig: 11 [#1]

      This patch fixes the issue by removing offending (and somewhat
      duplicate) code from init_phy() routine, and changes _probe()
      function to use uec_mdio_bus_name().
      
      Also, since we fully construct phy_bus_id in the _probe() routine,
      we no longer need ->phy_address and ->mdio_bus fields in
      ucc_geth_info structure.
      
      I wish the patch would be a bit shorter, but it seems like the only
      way to fix the issue in a sane way. Luckily, the patch has been
      tested with real PHYs and fixed-link, so no further regressions
      expected.
